Boom
Use shims (6) under the wear pads as required to maintain
a maximum gap of 0.06 in (1,5 mm) (7) between the wear
pad on the front and sides of the boom. The gap at the
rear of the boom should be no more than 0.12 in (3 mm).
Shims are available in four thicknesses, 0.02 in (0,5mm),
0.04 in (1 mm), 0.06 in (1,5mm) and 0.08 in (2,0mm).
3.4.3 Boom Wear Pad Lubrication
After replacing any wear pad(s), or after prolonged
periods of inoperation, light lubrication of the boom wear
surfaces with a factory authorized grease is
recommended to keep the boom wear surfaces
lubricated properly. Light lubrication of the boom wear
surfaces is also recommended when the machine is
stored, to help prevent rusting.
Note: The first shim next to the pad needs to be the one
with holes, instead of the slots.
